Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The uniformity of chemical liquid concentration in a work vehicle's storage tank can be compromised if not sufficiently stirred, leading to decreased work accuracy and potential clogging of spraying nozzles, especially at the start of spraying operations.
Innovation Solution
An automatic traveling method and system that includes a stirring processing unit to start stirring the chemical liquid in the storage tank before the work vehicle begins automatic travel, ensuring uniform concentration and preventing nozzle clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the chemical liquid is not stirred before spraying work starts, then the work vehicle can begin spraying immediately, but the concentration of the chemical liquid becomes non-uniform and nozzles may clog
Solution Approach 1:
The stirring operation is performed in advance before the spraying work begins. The control unit activates the stirring motor to mix the chemical liquid in the storage tank before the spraying pump starts operating, ensuring uniform concentration is achieved beforehand so that spraying can proceed immediately without interruption.
2Manufacturing precision
If stirring is performed before automatic travel starts, then spraying work accuracy improves, but additional time is required before spraying can begin
Solution Approach 1:
The system performs the stirring action in advance during the preparation phase before automatic travel and spraying begin. By automating this preliminary stirring step, the system ensures concentration uniformity is achieved before work starts, and the stirring occurs during a time when no spraying is yet required, thus not impacting the actual spraying productivity.
3Device complexity
If the chemical liquid sits in the storage tank without stirring, then the system remains simple and ready to spray immediately, but the chemical agent and liquid separate causing non-uniform concentration
Solution Approach 1:
The system includes an automatic stirring function that is activated by the control unit before spraying begins. The stirring motor and stirring blade work together to self-mix the chemical liquid, maintaining composition stability without requiring manual intervention. The system serves itself by automatically detecting when stirring is needed and performing the mixing operation.
